Creating the Christmas Vanilla Roll Cake can be easy if you follow these simple steps:

1. Preheat your oven: Set your oven to 375°F (190°C) and line a 15×10-inch jelly roll pan with parchment paper.
2. Prepare the egg mixture: In a large bowl, beat the eggs with granulated sugar and vanilla extract on high speed until thick and pale, about 5 minutes.
3. Mix dry ingredients: In another bowl, sift together the all-purpose flour, baking powder, and salt.
4. Combine mixtures: Gradually fold the dry ingredients into the egg mixture until just combined. Be careful not to overmix.
5. Spread the batter: Pour the batter into the prepared jelly roll pan and spread it evenly.
6. Bake: Place the pan in the preheated oven and bake for 12-15 minutes, or until the cake springs back when lightly touched.
7. Cool the cake: Remove the cake from the oven and let it cool in the pan for 5 minutes. Then, invert it onto a clean kitchen towel dusted with powdered sugar.
8. Roll the cake: While it’s still warm, carefully roll the cake up with the towel, starting from the short end. Let it cool completely in this shape.
9. Prepare the filling: In a separate bowl, whip the heavy cream with powdered sugar and a splash of vanilla extract until soft peaks form.
10. Unroll and fill: Once the cake has cooled, unroll it gently. Spread the whipped cream filling evenly over the cake.
11. Roll it back: Carefully roll the cake back up without the towel this time. Place it seam side down on a serving platter.
12. Dust with powdered sugar: For a festive touch, dust the top with powdered sugar before serving.
